Angular Resolution of Human Sound Localization
(2012-08-09)Sound localization is very important to the acoustic community due to its capacity to replicate audio environments. Surround sound systems, theaters, and audio engineers all use localization techniques to give a listener ... -
Band Gap Modulation in Single-Walled Carbon Nanotubes
(2011-02-08)Carbon nanotube (CNT) structures represent a recently discovered (1991) phase of carbon. The CNT structure is best described as a single graphene sheet rolled into a seamless tube. They can be classified into three ... -
Band Gaps of Single-Walled Carbon Nanotubes: A Computational Study
(2010-03-31)I studied the electronic band structure of carbon nanotubes through computer simulations using quantum molecular dynamics. I demonstrated that band gap energies can be "tuned" by the application of external tensile strain. ... -
Classification of Asteroid 9983 Rick Fienberg using B, V, and R Photometry
(2012-08-09)Asteroid 9983 was classified using BVR broad-band photometry. Observations were performed with the 0.9-meter WIYN telescope at Kitt Peak Observatory, the S2KB camera, and timed to occur at opposition. These observations ... -
Comparison of the Matter and Interactions and Traditional Instruction Physics Curriculums
(2012-08-09)This paper describes the comparison of the Matter and Interactions and traditional physics curriculums. The language, textbooks, and existing assessment instruments of the curriculums were the focus of the comparison. ... -
Computational Fluid Dynamics Model of a Cyclone Separator
(2011-02-08)Air cyclones are a promising technology for first stage air filtration in future lunar habitats where lunar dust mitigation is a mission critical concern. Our experimental work with cyclones in microgravity as part of ... -
The Dectability of Broad Absorption Features in Echelle Spectroscopy
(2011-09-02)In astronomical spectroscopy, echelle spectrographs are frequently used due to several benefits: the wide wavelength coverage they offer, efficient ... -
Determining the Cost Effectiveness, Emissions Reduction, and Power Consumption of Full Scale Adoption of the Electric Vehicle
(2012-08-09)The electric vehicle as a viable mode of mass transportation has not been previously investigated. This investigation combines the cost effectiveness, emissions of green house gasses, and national power generating capacity, ... -
Disappearance and Resurgence of Jupiter’s Southern Equatorial Band
(2011-02-08)Galileo’s first look at Jupiter through a telescope sparked his evidence that our solar system was heliocentric. Since then the observation of Jupiter has become incredibly widespread and frequent. Our initial goal was ... -
Improving and Characterizing a High Resolution Spectrograph For Use in Measuring the Zeeman Effect in Mercury Gas Emission Lines
(2010-03-17)We have built and calibrated a high resolution spectrograph capable of resolving 0.024259±3.24x10−6 Angstroms per pixel. With several improvements to the instrument as well as extensive focusing, we have greatly increased ... -
Inertial Filtration of Lunar Dust in Lunar Gravity

Investigation of Propellant Sloshing and Zero Gravity Equilibrium for the Orion Service Module Propellant Tanks
(2012-08-09)We study fluid slosh in the Orion Service Module propellant tanks. Resonant slosh frequencies were measured as a function of tank fill-fraction in a scaled model of the tanks. We carry out both computational and theoretical ... -
Modification and Reconstruction of Seismographs and Analysis of the Structure of Seismographs and the Local Seismic Activity in Southeastern Wisconsin
(2010-03-18)This project began with the reassembly of the Carthage College seismometers and en- hancing them to be more sensitive than they have been in the past. The potential seismic activity is collected as an electrical signal and ... -
Newly Recognized QSO/Galaxy Pairs at Small Impact Parameters for Low Redshift Galaxies
(2011-02-08)A search for emission lines in foreground galaxies, in QSO spectra (zgal << zQSO) of the SDSS data release 5, reveals 21 examples of QSOs shining through low redshift, foreground galaxies at low impact parameters (<10 kpc). ... -
Phase transitions in the Ising model with random gap defects using the Monte Carlo method
(2012-08-09)The Ising model, the simplest model of ferromagnetism, describes a magnetic lattice with nearest-neighbor interactions and is governed by Boltzmann statistics. The Monte Carlo method provides one approach to simulate ... -

Structural Analysis of NGC 2371-2 Using Deep Images in [O-III] and Tri-color
(2010-03-18)The odd structure of NGC 2371/2, a planetary nebula (PN) has been studied. This nebula has ejected gas during the final stages of stellar evolution. These gases do not appear to be symmetric as would be expected. Using a ... -
Theoretical Determination of the Radiation Pressure Inside of the NIF Hohlraum
(2010-03-17)The NIF facility was created to study fusion under controlled conditions. One hundred and ninety two of the world’s most powerful lasers are focused onto a very small gold cylindrical target. The high intensity laser heats ... -
Validation of Propellant Dynamics Model
(2011-02-08)n fluid dynamics, slosh refers to the movement of liquid inside a hollow object. We examine these dynamics in a scale-model of the Orion Service Module (SM) down-stream hydrazine propellant tank. The SM is a component of ... -
Webcam Observation of Saturn's C-Ring
(2011-02-08)Changes in the rings of Saturn are difficult to detect from Earth-based telescopes because of their fine composition. Particulate bodies, like planetary rings, demonstrate strange phenomena without obvious causes and are ...
